The main disadvantage of DBS is the cost. Currently, the cost of the device is approximately $10,000 per unit. Additional disadvantages include an increased risk of infection due to the presence of implanted hardware and the cost of maintenance (eg, repair or replacement of fractured wires or repeated office visits for stimulation adjustments). Currently, battery exhaustion necessitates replacement of the entire pulse generator, the most expensive component of the system (costing about $8000), every few years.
